Thank you for your response Gonzalo.
Currently I don't have the code using the problematic functions I state, I have
the code working (actually encoding the data to video file) by not using
av_find_stream_info and avcodec_decode_audio4, I'm currently using
av_parser_parse2 to get the mp3 data out of the pkt returned from fread and
then just writing this (via AVPacket) using av_interleaved_write_frame to the
output audio stream. I found av_parser_parse2 out of desperation when I
couldn't decode the mp3 data any other way.
The problem with the above way is I can only get mp3 codec to work properly in
outputted video file - if I use aac codec then I just get silence when playing
the video. The problem with mp3 audio in the mp4 video is that it doesn't seem
to play in all players on my pc, vlc is ok with it. maybe I'm using
av_parser_parse2 wrong??
I'm telling you this because I have already changed the code (to match
output-api.c/muxing.c/remuxing.c examples) so many times to try to decode in
the many ways I have stated and I know what I have stated is right without
changing the code back again to match the samples (I have done so 3 times
already today) (I hope you understand) - avformat_find_stream_info crashes for
mp3 only and avcodec_decode_audio4 returns header missing for mp3 file only.
av_read_frame crashes but av_read_packet doesn't.
I am using qnx platform which is arm linux.
Regards
Bradley

Bradley, more info is required. Can you post or upload a section of
your code?
